The following section explains about the case where the negative logic and the forward/reverse
rotation pulse trains are set to "_ _ 1 0" in [Pr. PA13].

(Note)
Note. Pulse train input interface is comprised of a photocoupler.
If a resistor is connected to the pulse train signal line, it may malfunction due to
reduction in current.
The following example shows that an input waveform has been set to the negative logic and
forward/reverse rotation pulse trains by setting "_ _ 1 0" in [Pr. PA13]. The waveforms of PP, PG,
NP, and NG are based on LG.
